2 The Silent Engineer Advises It is very important for the Leaving Certificate Engineering student to take the following advice into account before commencing work on the Design Project: Concentrate on the actual Design task element of the Design Brief as apposed to the Introduction (preamble). Be as broadminded and open in your interpretation of the Design Brief as possible. Immediately set about following the structure outlined in this presentation. Set a timeline and stick to it at all costs. Make use of all available workshop time. Finish on March 4 th Execute a simple, solid and functional design to a very high standard.

3 ENGINEERING - TECHNOLOGY PROJECT: DESIGN 150 marks - 25% It is important that all candidates read and understand the contents of the Engineering Technology Project document fully. For this presentation we will concentrate on: The Design Brief As well as all the general directions to candidates, pay special attention to the completion date.

4 Design Brief This is the preamble or introduction to the Design Brief. While this information may help to explain the Design Brief, it should not take your focus from the Design task in hand. While most of the preamble is just setting the scene for the Design Brief, you should identify any key words or phrases which may be worth investigating during your research

5 Design Brief This section identifies very clearly the specific Design task set by the Brief. To fulfil the Design Brief you must ensure your project meets these requirements exactly. Identify the key words and remember that this section will be the focus of your ANALYSIS and RESEARCH.

6 Design Brief A number of standard conditions and restrictions are attached to the Design Brief. You must note each one and adhere to them rigidly during the manufacturing process, otherwise marks will be lost.

7 Where to start... Immediately you should focus your mind on the Design Brief (What is a Model Electric Kart?) Set up an Engineering Technology Project 2016 folder with a Research subfolder on your desktop. Take the key words from the brief and use Google/Bing/YouTube to collect a bank of appropriate images, videos and information. This will start you thinking about the Design Brief and the images will be very useful when putting your research findings on paper. All research material can be stored in this folder.

8 Setting a Timeline Once this initial element of research is complete and you have a basic understanding of the Design Brief you need to set about structuring your Plan of Work for the project. A Timeline is ideal for getting yourself organised

9 The Design Portfolio 40 Marks % overall The Design Portfolio organises your thoughts and work sequence for the entire project. It gives you a logical structure for working through the design process. It is a very effective way of showing the examiner your thought process as you develop your prototype. A well thought out design portfolio can ensure that you don t loose marks in the event that your prototype is not fully functional, as a good portfolio will identify the problems encountered and propose effective solutions. A preferred Design Portfolio structure is suggested here and we will talk through the contents required for each section.

10 1. Design Brief 2. Investigation The Design Portfolio Contents 1. Analysis of Brief 2. Research 3. Possible Solutions 4. Final Design 5. Working Drawings (Including Materials List and Wiring Diagrams) 6. Manufacturing 7. Testing and Evaluation The Design Portfolio is divided into these seven headings. If followed in sequence they will guide you through the development of your concept design

11 1. Design Brief This section contains a full copy of the Design Brief It is critical that you continually reference and review the Design Brief to re-focus your thoughts and to ensure that you keep the project development on track with the requirements set out in the Design Brief.

12 2. Investigation The Investigation section is broken into two sub-sections: Analysis of Brief Research

13 2. Investigation Analysis of Brief (1-1 ½ Pages) The Analysis section allows you to dissect the brief in detail. You can firstly give your initial thoughts on receiving the Brief All key words and phrases need to be defined and discussed succinctly: Model Electric Kart, own unique design,rear wheel propulsion unit, all round shock absorbing protection system, steering mechanism, adjustable and fixed aerodynamic fixtures. While the Brief is quite broad in structure, you must make your interpretation of what is being asked very clear. However, do not restrict your design scope by taking too narrow an interpretation of the Brief Remember your finished project may not necessarily be a stereotypical Electric Kart, as long as you can justify its adherence to the Brief. Your timeline should be included at the end of this section.

14 2. Investigation Research (6-10 Pages) The Research section talks the reader through your investigation of the various aspects of the Design Brief. It must be your commentary on the research you undertook no copy/pasting of paragraphs from the web. All aspects of the brief must be covered. This section makes use of Google/Bing, YouTube and any other research medium available to investigate the Design Brief. Remember that your research is the catalyst for the development of your possible solutions, therefore the influences for your possible solutions should be evident in the Research section.

15 2. Investigation Research Sections of Research Describe an Electric Kart in detail with the aid of good quality graphical research material. The Evolution of Kart Design could be presented here also as referenced in the Introduction. Look closely at Similar Vehicles, other Concept Designs and Related/Similar Designs which may incorporate the features of an Electric Kart. Include individual sections researching Rear Wheel Propulsion Units, Shock Absorbing Protection Systems, Steering Mechanisms and Aerodynamic Features (Adjustable and Nonadjustable). The introduction to the brief suggests a number of additional areas that could be explored, such as Eco Friendly Automobiles and Safety Considerations. Look closely at methods of Automation and Control using electronics, pneumatics, gears, cams, linkages and any other suitable systems or mechanisms. Include a Personal/Action Research section where you show evidence of field research and include some evidence of correspondence with relevant companies or manufacturers. Make a Conclusion which will identify your Research section as the key influence behind the selection of your Possible Solutions.

18 3. Possible Solutions (6 Pages) In this section you must organise all your research and design ideas into 3 Possible Solutions. The Solutions must be presented graphically in the form of a neat labelled sketch/solidworks model. Reference any existing mechanism/thrill Machine which may have influenced your design. Give a detailed synopsis of each design solution. Remember you must pick a Final Design from one of your Possible Solutions. Your Final design may also be an amalgamation of two or more of your Possible Solutions.

19 3. Possible Solutions 2 pages per solution: Sample Layout of a Possible Solution Page 1 Explanation of solution and principal of operation. A picture of an existing model that influenced your design. Page 2 Detailed, labelled sketch or Solidworks model of the solution.

20 3. Possible Solutions This page shows a sample of sketched possible solution drawings for the Crane Vending Machine in There must be enough detail in the drawings to convey the concept of each design.

21 3. Possible Solutions A good example of a sketched Possible Solution from 2011 Model Snow Mobile

22 3. Possible Solutions Good examples of Possible Solutions using Solidworks from 2011 Model Snow Mobile

23 4. Final Design Very simply, this section is where the final production model is selected. It must be either: One of the 3 Possible Solutions/Concepts discussed in the previous section. or A combination of features from two or more of the 3 Possible Solutions. To follow the design process properly you must explain the development of your Final Design from the Possible Solution stage in your Rationale. A Final Design or Production Model drawing should be much more detailed than a Possible Solution drawing.

24 4. Final Design A good Final Design Section should include two key elements: 1. A detailed set of graphical representations of your Final Design Model showing as much detail as possible. 2. A detailed Rationale for your choice of model, indicating your thought process for selecting this particular design and your consideration for issues such as, adherence to brief, ability to manufacture, functionality, material selection, costing, etc.

26 5. Working Drawings Including Materials List and Wiring Diagrams The Working Drawings section should have detailed, dimensioned part drawings for each component manufactured in your project. Good quality working drawings will instruct someone in detail on how to make your project. A Materials List gives specific information for each part on one table and will include information such as Part No., Material, Sizes and Quantity. A good quality wiring diagram for each electronic circuit on your Final Design should also be included in this section.

27 6. Manufacturing The Manufacturing section gives a description of the main processes involved in manufacturing the Final Design. It shows the examiner that the project is your own individual work and that you can describe the manufacturing techniques used in detail. Pick four - five of the more challenging manufacturing process and with the aid of diagrams or pictures explain in detail how each process was completed. Lathework, milling, drilling, CNC machining, laser cutting, plastic moulding, plastic bending, threading, tapping, and specific benchwork tasks can all be selected as manufacturing processes to be explained. Taking pictures of these processes as you work through your project makes this section much easier to complete.

28 7. Testing and Evaluation On completion of your Final Design a thorough testing and evaluation must take place. There are two key points to be discussed in a good evaluation: Does my completed project fulfill the brief? What changes or alterations would I make to my design to improve its function? Remember that your Design Project is a first prototype and in engineering terms initial prototypes are seldom perfect. A good quality project with design/function problems can still receive an A grade if you identify design faults and propose effective solutions in the Testing and Evaluation section.
